How often does the way the compiler handle structs and array change? If
these remain constant (with the C type sizes) throughout the compiler
releases, the compiler-assembly interfacing would remain safe.
If the statement I have made is incorrect, please do tell. At the moment
I can't think of any compiler-assembly interfacing uncertainties.
